My First Lab STEM Starter Kit: Smartphone Microscope and 3D Slides review

As a child long, long, long ago, I remember longing for a microscope in order to study things that were too small for me to see and tragically, I never received one. I now have a marvelous stereo microscope but it is too large and heavy to carry around with me to investigate things while I’m outside. When the My First Lab STEM Starter Kit: Smartphone Microscope and 3D Slides came up for review, it piqued my interest. I eagerly volunteered to review this tiny microscope. After receiving it, I discovered that it is a clever little microscope that works well magnifying small objects, is easily portable, and it allows you to take pictures of your microscopic adventures using your phone’s camera. Perfect for a big kid like me.

What is it?

The My First Lab STEM Starter Kit: Smartphone Microscope and 3D Slides is a science, technology, engineering, and mathematics (STEM) kit that includes a clip-on smartphone (or other mobile devices) microscope and 3D slides. The slides are paperboard slides with small items glued to them to observe using the microscope.

What’s in the box?


  • My First Lab Smartphone Microscope (60x magnification – with the aid of your phone’s camera zoom)
  • LED light and UV light are attached to the microscope (LR1130 button cell battery is replaceable)
  • 3D paperboard slides which contain 15 specimens to observe

Design and features

The smartphone microscope appears to be made out of silver colored hard plastic. It has a clear plastic ring over the end of the microscope to protect the lens. The smartphone microscope is mounted to a white plastic clip and rotates at this juncture. The clip that holds the microscope to the mobile device has black foam padding on both sides. This keeps the microscope from sliding around on your device and it helps to avoid damaging your phone.

Attached to the microscope on a rocker mechanism is the LED/UV light. There is a cap/dial on the end of the light that you’ll need to twist (you might have to push in and twist) to turn on or off the lights or change the battery. To access the dial, you’ll first need to rotate the whole assembly out from under the clip.

In addition to the microscope, you receive 15 specimens to study mounted on paperboard slides. They include samples of salt, sugar, pepper, cotton, silk, wool, a feather, insect leg, animal hair, rocks, sand, broken shells, pine cones (seed?), seeds, and hair.In the photo above, you can see the microscope lens used for magnification.The above photo shows that the light contains three LED bulbs.

The center LED is the UV light.And the everyday use lights are the two outer LEDs.When the cap/dial is removed from the light, you can access and replace the LR1130 button cell battery when necessary.

How to use the microscope

 

The back of the packaging contains the instructions for using the microscope and LED lights. When you clip the microscope on your mobile device, you need to make sure that the microscope covers the camera lens. NOTE: Your camera lens must be within about 2.5 cm from the edge of your phone to use this microscope. The clip will not reach farther. Moreover, my phone only has one camera, so for those of you who have more than one, you may have to experiment which lens to place the microscope over.

The packaging also tells you the correct positions of the dial to turn on the UV light, turn off all lights, turn on the LED lights, and open the battery compartment.

First of all, you’ll need to turn on the LED lights to observe an object. Starting at the very top of the light is the UV light “On” position, the zero represents the “Off” position, the shining icon represents the LED lights “On” position, and the last position allows the cap to come off to replace the battery. To turn on the lights you’ll need to twist the cap to the desired lights “On” position. Again, you may have to push in and twist to do this.

Next, you need to clip the microscope lens over your mobile device’s camera lens.
Finally, to view any specimen, you must place the end of the microscope’s clear plastic ring directly onto the surface containing the specimen to obtain a clearly focused subject. You may increase this distance a maximum of 1 cm by gently pulling the microscope away from the clip, though I never needed to do this. This ring not only protects the microscope lens but also helps place the specimen at the correct distance from the microscope for the clearest view.

Use

When I first used the microscope with my Pixel 2 XL, I used it to study all of the specimens on the prepared slides. The above photo illustrates the magnified view of the insect leg specimen included in the kit. The above photo does NOT include any additional magnification from my camera’s zoom. I used my phone’s camera to take a photo of the microscope’s magnified view. I think this magnification is about 10x.

Even though the microscope says it magnifies objects by 60x, I think the My First Lab company assumes that you have a camera zoom and takes that into account when calculating the total magnification of the microscope. That means if the microscope has a magnification of 10x and your phone magnifies 6x, then the total magnification is 10 x 6 = 60x. This is why I think the microscope, by itself, magnifies 10x.
My Pixel 2 XL magnifies objects by 7x, so my total magnification may be about 70x as shown above.

The above photo is actually the pollen comb of a honey bee’s hind leg. It is also the first tarsal segment of a honey bee foot. The bee brushes all the pollen off her body and places it in the pollen basket just above this segment. Those are the clumps of yellow you see clinging to honey bees’ hind legs. Unfortunately, the rest of the foot (tarsal segments) of the bee’s leg was broken off on my specimen. But WOW, it’s fascinating being able to see the detail of the pollen comb using this tiny microscope’s full magnification!

The next few photos are of insects from an insect collection I made while in graduate school studying entomology.

This is a normal photo taken of a sulfur butterfly (family Pieridae). My camera was about 5″ away from the subject. You can tell the butterfly’s relative size when compared to a quarter.Using just my camera’s maximum magnification (7x) without the microscope, this is what the butterfly’s wing looks like with the quarter in the background.This is the view of the wing after attaching the microscope to my phone (without camera magnification).
This is the view through the microscope with the addition of my camera’s maximum magnification. It is difficult to get a crystal clear, focused picture of any specimen using the maximum magnification of this microscope. However, it makes a great companion while you explore the outdoors because it is small and portable.

My larger, heavier microscope has infinitely better optics and provides 90x magnification to obtain a crystal clear magnified image. However, I do not have the equipment to take photos of what I see while using my larger microscope.I took a picture of another area of the wing using maximum magnification (microscope + my camera’s zoom). Look at the details of the scales and the fringes of the wings! Isn’t that magnificent?Next is a photo of an iridescent bee from the insect family Halictidae (the family of sweat bees). This photo illustrates how large this bee is in relation to a quarter. My camera was about 5″ away from the bee.This is another photo of the bee using my camera’s maximum magnification (without the microscope).I then attached the microscope to my phone and took a photo (no additional magnification from my phone’s camera).
Here is the same bee magnified to about 70x (microscope + camera magnification). I really like this little microscope! You can tell that the compound eye is made up of hundreds of ommatidia – so cool.

Overall, I found that the microscope worked really well for me as long as I placed the clear plastic ring directly on the surface containing the object I wished to see. Every now and then, the LED lights flickered but this was easily addressed by adjusting the dial on the light. I did not use the UV light, but you could use it to look at the patterns on flower petals that only show up under UV light.

What I like

  • The microscope and LED lights work well
  • Microscope magnification + phone magnification ≅ 60x total magnification
  • You may use your phone’s camera to take pictures or videos of your specimen
  • There’s foam padding on both sides of the clip to keep the microscope from sliding around and to prevents scratches
  • It seems durable
  • It’s small and portable
  • Inexpensive

What needs to be improved

  • Don’t expect crystal clear images when using the highest magnification
  • Your camera lens must be within about 2.5 cm from the edge of your phone to use this microscope

Final thoughts

I really enjoyed using the My First Lab STEM Starter Kit: Smartphone Microscope and 3D Slides. The kit includes a small microscope that is perfect for kids ages 6 and up (or big kids like me). In addition, the kit also comes with five prepared paperboard slides which have a total of 15 specimens to study. However, it is important to know that the purpose of the microscope is to magnify macroscopic objects or organisms (things that can be seen with the naked eye). It will not magnify microscopic organisms enough to for you to see (like those in pond water – you’ll need a compound microscope for that).

This microscope is easy to use; works well; is small, portable, and durable; allows you to take pictures of your microscopic adventures (YES!!); and has a replaceable battery for the LED lights. I would have LOVED receiving this as a kid!

NOTE: you may purchase just the microscope without the slides for only $11.

Price: $17.99 (kit) or $11.00 (microscope + LED light only)
Where to buy: Amazon (kit) or Amazon (microscope + LED light only)

TaoTronics standing desk review

The TaoTronics Height-Adjustable Standing Desk provides great value in a space-saving vertical lift design. Whether you are looking for a boost in productivity or exploring the health benefits of standing, this desk will be a great addition to your home or office workspace.

What is it?

The TaoTronics Height-Adjustable Standing Desk is a pneumatic assisted standing desk converter that lifts and lowers smoothly to any position you need. Switching from sitting to standing is as easy as a press of a lever.

What’s in the box?

Standing desk
Keyboard shelf
Brackets, Screws and Hex Keys
User Guide

Design and features

The TaoTronics standing desk features a space-saving vertical lift design which doesn’t encroach on your floor space like some other designs that move outward when raised. Raising straight up above your normal workspace, it provides a compact and ergonomic workspace.

Supporting up to 80 lbs, the standing desk is strong enough for multiple monitors, speakers, and more. The desk also has a height range of up to 12 inches above your desk surface.


The desk’s upper surface footprint of 32 x 24 inches provides a lot of surface space for all the things you might want to have at eye level, However, this may also be a disadvantage for some people that may not have a desk that is very deep. The desk requires a 23 x 25 inch area to sit on, and the total area of the upper surface and the keyboard shelf is 32 x 33 inches.

The desk is operated by squeezing the levers on each side and pulling up or pushing down. This is somewhat of a disadvantage to an electrically operated desk, as it requires both hands to operate. The upside to this type of mechanism is that it’s much faster to operate than an electrical one.


The keyboard shelf is adjustable by simply turning a knob, and is also easily removable if you wish to use your keyboard on your desk surface or on the surface of the standing desk.

There’s also a slot in the upper desk surface, it’s for tablets and phones. That’s a pretty handy feature. There are no monitor arm mounting holes, but the frame design does allow for a clamp-style monitor arm on the back edge.


What I like

  • Large footprint
  • Option to easily remove the keyboard shelf
  • Tablet and phone slot
  • Beveled edges
  • Range of adjustment
  • 80 lb capacity
  • Excellent height range
  • Ease of assembly
  • Sturdiness

What needs to be improved

  • Lift mechanism requires two hands to operate.
  • Sometimes sticks slightly when at the lowered position.
  • No monitor holes for a monitor arm.
  • No cable routing. You’re pretty much left to yourself on figuring out where to run the cables for your computer equipment. Although a few zip ties help, it would be nice if it included some kind of cable routing solution to both make it easier and neater.

Final thoughts

With the plethora of standing desks on the market today and the various designs and mechanisms they employ, you’ll probably want to do some research to see which one would best fit your needs. That being said, you’d probably be pretty happy with this one.

Price: $249.99

Wofalodata Fast Wireless Charger review


What is it?

The Wofalodata Fast Wireless Charger is a 2 in 1 wireless charging pad with a kickstand that meets the QI fast charging technology standard.

What’s in the box

Package contents:

1 x Wireless charger
1 x Kickstand
1 x Micro USB cable
1 x Instruction booklet

Design and features

The Wofalodata Fast Wireless Charger is a small and compact wireless charger that conforms to the QI wireless charging technology standard. It is made up of a wireless charging pad and a removable kickstand that can be neatly tucked away in the back.

On the side, there is a micro USB port that accommodates the included micro USB cable to supply power to the pad for charging.

On the front of the charging pad, there is a LED light. When the charger is first plugged in, the LED blinks red and then goes to a steady blue when it is ready to provide charging. The instructions suggest that you can place your phone in a horizontal or vertical position, but I found that with my iPhone 8Plus, it was awkward and would tend to want to tip over. The vertical position did not seem to allow the larger phone to make good contact with the charging pad. Horizontally, it fit well, but that is as far as the good news goes when trying to charge my iPhone 8Plus. Once I placed my phone to charge, it would initially charge for approximately 2 minutes with the steady blue LED light, and the blue LED would start blinking for about 90 seconds and then the LED would turn red and the phone would stop charging. After a few seconds, the LED would turn blue again, and start charging again. This cycle of events continued until I removed the phone from the charger, and occurred each of the dozen or so times I tried.
Now it is important to note that I have at least 3 other Qi wireless charging pads, 2 of which are cheap no frills pads, and one is a more expensive Samsung pad. Irrespective of the make, they all perform flawlessly. This issue that I experienced with this charging pad is unexplainable.

After deciding to no longer risk trying to charge my iPhone on this pad, I tried an old Samsung Galaxy 6 phone, and that worked without issue. In about 30 minutes, the Samsung charged approximately 30 percent.

What I like

  • Wireless charger is lightweight
  • Nice and convenient Kickstand

What can be improved

  • Wireless charger must be able to charge all cell phones that meet the QI wireless charging standards.

Final thoughts

There are numerous inexpensive wireless chargers available today, and each one needs to meet the basic criteria for wireless charging to be considered for purchase. While this charger is lightweight and has a nice compact form factor, the issues I experienced with it when trying to charge my iPhone 8Plus, make it a “no go” for me.

Price: $12.99
Where to buy: Amazon

Twelve South SurfacePad iPhone 7 Plus/8 Plus case review

As we mentioned in a recent news post, the SurfacePad for iPhone is a thin, minimal leather cover for your iPhone 7/8, iPhone 7/8 Plus, or iPhone X.  It protects the front and back of your phone from pocket hazards and from getting surface scratches from tables and countertops.  Twelve South was kind enough to offer a SurfacePad to The Gadgeteer for review, and I was selected to put the cover for the iPhone 8 Plus/7 Plus to the test.

Hardware specs

  • Ultra-thin, full-grain leather cover
  • Applies like a screen protector, with an adhesive pad instead of a shell case
  • Hands free viewing & display stand
  • 2 card slots to streamline your everyday carry
  • Qi charging compatible for iPhone 8
  • Thickness: .07 inches (2 mm)
  • Weight: 1.6 ounces (45.3 g)

Design and features

I received the SurfacePad for iPhone 7 Plus.  I requested and received the deep teal color.  The case is very well made, with even, self-colored topstitching.  The phone’s screen is completely covered;  a cutout on the back leaves the back camera, flash, and microphone uncovered.  The double-row topstitching on the back acts as a hinge for using the SurfacePad as a horizontal stand for the iPhone.

Setup

There really isn’t a lot of “setup” involved, but you should make sure that the back of your phone is clean and dust-free for best adherence of the sticky pad.  Luckily, the adhesive that holds the case in place is removable, repositionable, and reusable, because it took me a couple of tries to get the phone centered and affixed to the case just as I wanted it.  There’s a video at Twelve South to show you how it’s done.

Performance

There are two slip pockets for IDs or cards that aren’t filed in your iPhone’s Wallet app.  You can see more of how the back is attached so it can be folded into a horizontal stand, which we’ll see later.

The front of the case is embossed with the Twelve South logo.  The interior of the front cover is branded with the SurfacePad name, and the Twelve South logo is under the adhesive pad flap.

You can see the interior edge with the silence slider and the volume buttons.  The leather is soft enough that you can operate the volume buttons through the closed case.  You’ll be able to adjust your playback volume while listening to music, or you could even trigger the camera release through the case if you don’t need to see the screen while you’re taking photos.

When I was taking photos with the back camera, I let the front cover hang down and I held it like a camera grip in my left hand while I operated the on-screen camera release “button” with my right.

You can see that some of the metal side is left uncovered by the leather hinge.

Even when closed, you can see that the entire side with the power button is left uncovered.  This of course makes it easy to access the power button, even when the case is closed.

The metal of the top and bottom is also left uncovered, which leaves a lot of metal open to scratching, but it also means you can hear the speakers and use the charging cable unimpeded.

The leather hinge is flexible enough that you can fold the case completely to the back to hold and use the phone one-handed.  I found it comfortable enough to hold for a couple hours on a call.

The case was also useful as a horizontal stand.  It was nicely stable in this position.  I could even tap on the screen while it was standing like this without fear of it tipping over.

What I like

  • Attractive leather case that protects the screen as well as the back
  • Front cover folds to the back for one-handed holding and use
  • Can be used as a horizontal stand
  • Room for two cards if you like to use your phone case as a minimal wallet
  • If your phone allows it, the cover is Qi-compatible for wireless charging
  • Adhesive pad adheres strongly to the back of the phone, and it can be removed without residue

What needs to be improved

  • Not really a needed change, but be aware that folding the front cover back will block the back camera

Final thoughts

The Twelve South SurfacePad is a beautiful, protective cover for the Apple iPhone 7 Plus.  It protects my screen in my purse, it serves as a horizontal stand, and it looks good doing it.
Price: $49.99

DrinKup smart water bottle review

I have never been a big water drinker unless I was working out or physically working on something that was making me sweat.  Now living in south Texas that can be easily achieved by stepping outside.  However, working in a cubicle farm every day in my 7:30 – 4:30 office job never really required me to drink much if any water.   When I did make myself drink more water I seemed to be more focused on it in the morning hours and just before lunch.  Once I came back from lunch, I rarely ever drank any water.  I do know that I was finding myself to be very tired at the end of a work day which was probably a byproduct of being dehydrated.  Luckily for me, I received the opportunity to try out the new DrinKup smart water bottle.  It is supposed to remind you when to drink and keep you hydrated for the time periods you specify.  Let’s see how that worked out for me.

What is it?

The DrinKup Smart water bottle is a water bottle that is supposed to track your hydration levels throughout the day.  It tracks them by using a ‘smart’ bottle cap on the bottle that measures how much water you have drunk.  It has an associated app that works on iOS and Android that allows you to enter in drinks you have outside of the bottle and track things like exercise so it knows if you need more or less water during the day. Please excuse the line you see going through the middle of the box.   I apparently overindulged when it came to opening the outside packaging and cut through a bit too far into the actual item box.

Hardware Specs

It comes packaged in a really nice box and is available in four different colors (yellow, red, white and blue).  The aluminum bottle cap includes a touch sensor screen with a LED display and a rechargeable battery.  The bottle is stainless steel with a 316 double wall vacuum insulated body.  It is supposed to keep cold water cold up to 24 hours and hot water hot up to 12 hours.  I have left water with ice in it at 4:30 pm and come in the next day at 7:30 am and there is still ice in the bottle.  The bottle is also BPA free.  The bottle will hold 17oz or 500ml of liquid. The battery is rated to last up to 2-3 months depending on how much you use it.  The app does show a battery level indicator in it.  You can see that you charge the bottle cap via a USB port in the lid.  This port is covered by a rubber cover and you then must twist the lid to fully cover the port when charging is complete.

What’s in the box?

Inside the box, you will find three items.

  1. The water bottle with the lid attached.
  2. A quick user manual
  3. A USB cable for charging the lid

Design and Features

The first thing I had to do was to charge up the water bottle cap.  I plugged the USB cable into the port on the bottle and put the other end into a USB socket on my wall outlet.  You can see from the image above what it looked like when charging.    When charging was complete the display no longer showed the battery.   Once the cap was charged I downloaded the app onto my phone.  I am currently running a Samsung S9 so I downloaded the Android version.

The first screen asked me to log in or create an account.  I clicked the create account button and received the following screen below.

I entered my email, password and agreed to the terms and conditions.  Once done I clicked the ‘next’ button.

The next page asked me to fill in basic profile information.  I do have a couple of issues with this page.   The height would only allow me to enter in my height in decimal feet.  It would have been much easier to enter 5ft 7in rather than 5.58.  I am sad to admit I had to find a Google converter to figure that one out.  I really do not like math!   My other complaint has to do with the record period.   This is the period of time in which the bottle will nag you to drink if it feels you are dehydrated.   It only lets you put in whole hours.  I wanted to track from 7:30 am to 4:30 pm but had to stick with 7 am to 5 pm.  It should be noted that the ID field is how you can get friends to find you on the app.  Once set it cannot be changed.  The display name is just the name the app will display on the home page of the app.  I then chose the option to pair the bottle.  At this point, I had to put the cap on the bottle to activate it.  The app found the bottle pretty quickly and I gave my bottle a name.   Note that it is on the bottle settings page where you can apply firmware updates to the cap itself.

As my day went along I would periodically be reminded to drink up.  The bottle cap will vibrate pretty quietly 3 times and you will get a notification on your phone.   It is pretty quiet, but I have to admit if you are in a meeting and only one person is talking everyone around me did notice.   Fortunately, there is a setting under the bottle settings that lets you turn off the lid vibration.  Each time I drank, I put the lid back on.  Within 5 seconds or so, I would hear a high pitched electrical whine and then the display would show how hydrated I was.  The above picture is showing the display indicating I was 80% hydrated.   Notice the black dot on the top of the display.  I actually put that there with a permanent marker.  There is no way to tell which way is the right way ‘up’ so when the devices display the percentage, half the time I was trying to read the results sideways or upside down.  You are supposed to be able to tap on the cap with your finger at any time to display your hydration level.  I found this to be a bit hit or miss.

The above picture shows my hydration graph for a single day.  You can see when it starts to drop around 80% it will notify me to drink up.  At that point, you see the jump in the hydration level.

What I like

I love that the lid will stay charged for such a long period of time.  I have used it for a little over a week and it just lost one of the bars on the battery.  It does do an excellent job of keeping me hydrated.  I forgot to mention that the app will connect to Fitbit and Apple watches.  I have neither one, but according to the website, once connected the app will prompt you to drink more if it knows you are being more active.   It does give you the ability to manually enter an exercise in 30-minute intervals from 30 to 300 minutes in categories of low, medium or high intensity.  I used that and did notice the amount of nagging to drink did increase.  The other thing I like is the app gives you the ability to enter in drinks taken without the bottle.  Maybe you go to lunch and have a glass of water for lunch.  You can manually enter that into the app.  The app also lets you connect to friends who also have a DrinKup bottle which could make staying hydrated a bit more fun.  Finally, the app will let you know if the water in your bottle has gone stale.  I left the bottle over the weekend at work.  When I got back on Monday it was flashing an X to indicate that I had stale water and should refresh it.

What needs to be improved

This bottle is pretty darn pricey for what it is.  I could only find this water bottle for purchase on the DrinKup bottle website and they charge $79 for the bottle.   I know there are apps out there that will remind you to drink no matter what device you are drinking from, but this could be good for those times you don’t have your phone with you.  The couple of issues I mentioned with setting up my profile in the app could be corrected – allow half hour increments in tracking period, allow height in feet and inches.  Another thing that could be made to work better is the ability to tap on the cap and display your hydration level.  I found myself tapping multiple times with the flat of my finger as described in the FAQ before I could finally get it to display.   Finally, they could put an indicator on the top of the bottle to show where the top of the display is located.

Final thoughts

I can say for certain that this bottle did an excellent job of keeping me hydrated.  I think a few things could be fine tuned in the app that would make it a whole lot more usable.   I do think the bottle and app are priced quite a bit higher than I would ever pay to get one.   I would recommend this to folks who feel like they have the $79 to burn, but I don’t think too many people would be jumping at the opportunity.

Price: $79
